The construction of the frame requires multiple pipes to be assembled together. The vertical pipes and vertical pipes are connected through horizontal pipes. The two ends of the horizontal pipes are welded to the two vertical pipes respectively. After welding, the size of the frame is fixed, so that one frame can only Corresponding to one set of horizontal pipes and one set of vertical pipes, the versatility is poor. In the related art, a connecting column is provided between the horizontal pipe and the vertical pipe. The connecting column has a solid structure and is inserted into the horizontal pipe. However, the shape accuracy error of the solid connecting column is large and cannot connect well with the inner wall of the horizontal pipe. There is a large gap between the two, resulting in poor connection between the horizontal pipe and the vertical pipe.

To this end, as shown in Figures 1 and 2, there is a pipe connector proposed by the present utility model. The connector 200 includes a folding plate portion 210 and a flat plate portion 220. The folding plate portion 210 is formed by bending a flat plate. The folding plate portion 210 is provided with at least one corner structure. One side of the flat plate portion 220 is fixedly connected to the folding plate portion 210 , and the other side is in contact with the outer wall of the fixed tube 100 . Specifically, the folding plate portion 210 is plugged into the connecting pipe 300 . After plugging, the outer wall of the folding plate portion 210 is in contact with the inner wall of the connecting pipe 300 . The flat portion 220 is provided with a fixing hole 221 for connecting with the fixing tube 100 . The fixing hole 221 is located outside the connecting tube 300 to facilitate fixing the flat portion 220 to the fixing tube 100 . It should be noted that the folding plate part 210 is plug-fitted with the connecting pipe 300, and the connection and disassembly of the connecting pipe 300 is relatively convenient. It can be conveniently connected to the connecting pipe 300 of different lengths, and is suitable for building various The folding plate portion 210 is easy to process, has a good appearance, can better contact with the inner wall of the connecting pipe 300, and has a good connection effect with the connecting pipe 300.

Optionally, the folding plate portion 210 has a concave structure. For example, the folding plate portion 210 is U-shaped and has two corner structures, or the folding plate portion 210 is L-shaped and has one corner structure. It is easy to understand that no matter whether the folding plate portion 210 is U-shaped or L-shaped, in addition to contacting the adjacent side walls of the connecting pipe 300 through the corner structure, the overall length of the folding plate portion 210 before the bending process can be controlled to make the folding The bent side walls of the plate portion 210 are respectively in contact with the inner walls of the connecting pipe 300 to achieve insertion and positioning of the connecting pipe 300 and the folded plate portion 210 .

In some embodiments, referring again to Figures 1 and 2, the connecting pipe 300 is in a square shape, and the folding plate portion 210 is provided with four corner structures. The folding plate portion 210 is in contact with the four inner corners of the connecting pipe 300, and further, After the folding plate portion 210 and the connecting pipe 300 are plugged in, they fit more closely and the installation is more stable.

In some embodiments of the present invention, as shown in FIGS. 1 to 3 , the fixing hole 221 is located below the connecting pipe 300 . After the connecting pipe 300 is installed, when the user stands normally and looks down, the connecting pipe 300 can block the fixing hole 221 to a certain extent. After the fixing pipe 100, the connecting piece 200 and the connecting pipe 300 are spliced, the whole is more beautiful. Specifically, the fixing hole 221 is provided with a blind rivet nut 110, and the flat plate portion 220 and the fixed tube 100 are riveted through the blind rivet nut 110. The structure is simple and the fixing is convenient. The user can quickly fix the flat plate portion 220 and the fixed tube 100 through the blind rivet nut 110 by using a riveting tool. Furthermore, there are multiple fixing holes 221 , and the multiple fixing holes 221 are arranged at linear intervals. It is easy to understand that there are two ways of riveting: fixed riveting and movable riveting. When there is only one fixing hole 221, the flat part 220 and the fixing tube 100 are fixed and riveted through the blind rivet nut 110. When there are multiple fixing holes 221, the flat part 220 and the fixed tube 100 can be movable riveted through the blind rivet nut 110, and the flat portion 220 and the fixed tube 100 can also be fixed.

In some embodiments of the present invention, as shown in Figures 1 and 2, the protruding length of the folding plate portion 210 along the thickness direction of the flat plate portion 220 is A, and the length of the connecting tube 300 is B, satisfying: A≥0.1 *B, ensure the effective matching length of the folding plate portion 210 and the connecting pipe 300, and the folding plate portion 210 can better support the connecting pipe 300.

The folding plate portion 210 and the flat plate portion 220 are welded and fixed. Compared with the detachable connection using screws, the connection between the folding plate portion 210 and the flat plate portion 220 after welding is more secure. Among them, the folding plate portion 210 and the flat plate portion 220 are both steel plates. Before the folding plate portion 210 and the flat plate portion 220 are combined, the folding plate portion 210 and the flat plate portion 220 can be bent independently, making the processing more convenient. Furthermore, in order to achieve more accurate positioning between the folding plate portion 210 and the flat plate portion 220, one of the folding plate portion 210 and the flat plate portion 220 is provided with a plug-in portion 211, and the other is provided with a plug-in slot 222. The plug-in portion 211 is plug-fitted with the plug-in slot 222. Specifically, referring to Figure 2 again, the folding plate portion 210 is provided with a plug-in portion 211, and the flat plate portion 220 is provided with an plug-in slot 222. Through the plug-in portion 211 and the plug-in slot 222, the folding plate portion 210 and the flat plate portion are plug-fitted. 220 plug fit, better welding effect after plugging. Moreover, the flat plate part 220 is a flat plate, and the insertion slot 222 is provided on the flat plate part 220. There is no need to process additional protrusions, and the structure is simpler. Furthermore, there are a plurality of plug-in parts 211 and a plurality of plug-in slots 222. The plurality of plug-in parts 211 are arranged at intervals along the circumferential direction of the folding plate part 210. The plug-in slots 222 and the plug-in parts 211 are arranged in one-to-one correspondence. Furthermore, The folding plate part 210 and the flat plate part 220 have a better insertion and positioning effect.

In some applications, referring to Figure 3, the frame includes a horizontal frame 400 and a vertical frame 500. The upper part of the vertical frame 500 is connected to the horizontal frame 400 and used to support the horizontal frame 400. However, the horizontal frame 400 is attached to the connecting pipe 300 on the top of the vertical frame 500. It is inconvenient to splice the connecting pipe 300 from above. To this end, by using the aforementioned connecting piece 200, the movable pipes can be spliced in the horizontal direction, thereby reducing the interference of the horizontal frame 400 on the splicing of the vertical frame 500.

The embodiments of the present utility model are described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, other modifications may be made without departing from the purpose of the present utility model. Make various changes.
